The rim of Liebig has a low inner wall, with an interior floor that is nearly featureless except for a few tiny craterlets. It is nearly, but not quite circular, with outward bulges to the west and southeast. The small, cup-shaped crater Liebig A lies along the inner wall and part of the interior floor.
The western edge of the Mare Humorum is a fault line designated the Rupes Liebig, named after this crater. This fault extends for about 180 km along the shore. To the southwest, in the section of lava-flooded surface between Liebig and de Gasparis, is a system of rilles named the Rimae de Gasparis. These cover an area with a diameter of 130 km.
